RAIL AND RAIL-CHAIR.

SPECIFICATION forming part of Letters Patent No. 427,348, dated May 6, 1890.

Application tiled April 2, 1888. Serial No. 269,282. (No model.)

T all whom it may concern,.-

Be it known that I, ARTHUR J. MOXHAM, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Rail-ChairlVedge for Street-Railroads, which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to provide a wedge suitable for a rail and chair, whose shape shall be such as to require a chair of only comparatively light weight while preserving great strength and rigidity, and at the same time present no obstruction to the blocks or sets of street-paving.

The invention will iirst be described in detail, and then particularly set forth in the claim.

In the accompanying drawings, Figure l illustrates the chair in end elevation, showing the rail in crosssection secured ,to t-he chair. Fig. 2 shows in side elevation the parts illustrated in Fig. l, viewed from the right. Fig. l3 shows a horizontal cross-sec# tion taken at the line X X of Fig. l. Fig. 4 shows in perspective a modiiied form of the key or wedge shown in the other figures for securin g the rail and chair together.

In said figures the several parts are indicated by letters of reference, as follows:

The letter C indica-tes the chair, R the rail, and IV a wedge for securing the chair and rail together. The rail R is provided with lugs P S under its head and tram, and with a bulb r on the loweredge of its web, and the chair C is provided with a recess or opening p p', wherein the rail rests when fastened in place.

In adjusting the chair to the rail the chair is tilted suiiiciently to permit the bulb r of the rail to enter the upper part of said opening or recess in the chair. The chair is then turned straight and pressed toward and against the rail until the bulb on its web rests on the bottom of the recess in the chair. The wedge IV is then inserted between the web of the rail and the side of the recess in the chair, which is of the same taper as the wedge, and driven up tight, forcing the upper parts of the chair outward against the sides of the pocket-s under the head and tram of the rail formed side of the bulb r of the rail can be entered under the bulb Y of the chair before coming in contact with the bulb projection V of the other side of the chair. By this means the rail can enter the chair with a much less width between the points p p than would be the case were this offset position of the points V and Y not secured. A great saving of weight and consequent cost is thus secured.

The wedge WV is made thinner in its int-erior partthan on its edges and ends to permit of the stamping or punching out of the tongue T, Figs. l and After the wedge is driven tightly to its place this tongue T is bent out and around the nearest edge of the chair, as shown in Fig. 3, thereby preventing its Withdrawal without great force or the use of tools. An opening o, Fig. 4, is provided in the wedge IV, in which a bar may be inserted topry out and bend the tongue T over the edge of the chair, as just described.

The chair C is securedl to cross-ties in the usual manner by spikes or otherwise through holes 71., and is provided with braces B B to give it the necessary strength and rigidity.

In Fig. 4 the form of wedge shown can be rolled in continuous bars. Said form, it will be observed, can be much modified and still retain the advantage of being rolled. The method of punching out and forming` the tongue T is also clearly illustrated in thisl figure.

Having thus fully described my said wedge for rail-chairs, as of my invention I clai1n- A chair-wedge for securing a rail and chair together provided with a stamped-out tongue and hole, as 07 for the entry of a turning bar or wedge, substantially as set forth.
